All three of the carrier rocket "proton-M", which found faulty components of 2015-2016 of production, returned from Baikonur to Moscow for repairs, told RIA Novosti the representative of the press service of the Roscosmos.
According to him, one of these missiles have already been repaired, sent back to Baikonur in late July with her help, was successfully launched telecommunications satellites, "Express-80" and "Express-103".
The state Commission at the Baikonur cosmodrome gave the nod to the start of the carrier rocket "proton-M" with telecommunication satellite "Express-80" and "Express-103" the removal of which in orbit will take a record 18 hours, according to "Roskosmos".
"The state Commission made a decision about filling the carrier rocket "proton-M" propellants and confirmed start time", - stated in the message on the website of the Corporation.
Note to the control system upper stage "breeze-M" was the reason for the postponement of the launch of the carrier rocket "proton-M" with telecommunication satellite "Express-80" and "Express-103" from the Baikonur cosmodrome with 30 to 31 July, reported RIA Novosti source in the space industry.
Previously, Roskosmos announced that the launch of "Proton" postponed for a day for additional inspections of components and assemblies.
Telecommunications satellites, "Express-80" and "Express-103", which is scheduled to launch from the Baikonur cosmodrome on Thursday, is scheduled to be operational in January-February 2021, said operator - enterprise "Space communications".
According to Roscosmos, the launch rocket "proton-M" with satellites is planned July 30 at 0.27 GMT.
The launching into orbit telecommunications satellites "Express-80" and "Express-103", which on 30 July launch rocket "proton-M" will become the longest in history.
As reported on Sunday, "Roscosmos", the "separation of the spacecraft "Express-80" from the upper stage "breeze-M" is expected in 17 hours 59 minutes after the start, "Express-103" another 17 minutes."
Roskosmos confirmed that the rocket "proton-M" with telecommunication satellite "Express-80" and "Express-103" starts at 00.27 MSK on July 30.
Earlier, a similar launch time called RIA Novosti source in the space industry.
Postponed from March due to a detected marriage of the rocket-carrier "proton-M" from Baikonur with the telecommunications satellite "Express-80" and "Express-103" planned for 30 July, reported RIA Novosti the representative of the press service of the Roscosmos.
This will be the only launch of "Proton" in 2020. Earlier this year was planned the launch of "Proton" with the Russian-European Mars ExoMars landing station, but it was postponed to 2022. In addition, for 2021 have moved the launch on Proton module "Nauka" for the International space station.
Reducing the cost of production of the rocket "Angara-A5" from 7 to 4 billion is not possible, said RIA Novosti member of the Russian Academy of cosmonautics named after Tsiolkovsky, chief analyst of the Association "Digital transport and logistics" Andrei Ionin.
Informed of the financial report of the Khrunichev Centre, it became known that the cost of manufacturing of the carrier rocket heavy class "Angara-A5" is 7 billion rubles, that is three times longer than flying from the Soviet era to the Proton the same capacity. By 2024 it is planned to reduce the cost to 4 billion. Roskosmos explained that the high cost stems from the fact that its Assembly is carried out in two cities - Moscow and Omsk, as well as boxed by the manufacturer. After the transfer of all production in Omsk and move to mass production price of the missile, as promised in the Corporation's approach to the market.
The cost of manufacturing of the carrier rocket heavy class "Angara-A5" is seven billion rubles, which is three times more than the rocket "proton-M" which it will have to be replaced, should the financial report of the Khrunichev Centre for 2019.
As noted in the document, implementation of measures will allow to reduce the cost of "Angara" by 2024, up to four billion rubles.
Russian module Nauka is planned to send to the Baikonur cosmodrome in July, to launch to the International space station, said the General designer of KB "salute" of Khrunichev Centre Sergey Kuznetsov.
It is noted that in the past week have been completed leak tests of the module body of "Science" and its docking units, and confirmed the operation of the pneumo-hydraulic propulsion system and external hydraulic circuits. In a vacuum chamber held pneumovacuum tanks tests module.
